The Diablo III Website announces a new automatic patch is now available for Diablo III to update Blizzard's action/RPG sequel to version 1.0.3.b. This is for the Americas, and users are warned this will interfere with cross-region play until all territories are in sync. Here are the patch notes:

Auction House

Bug Fixes

The "Bid" and "Buyout" buttons will now be correctly grayed-out in the confirmation window when attempting to purchase an item with insufficient gold

Bug Fixes

General

Fixed a bug where leaving a heavily-populated General chat channel would prevent players from rejoining any General chat channel until they logged out and logged back in

Fixed several tooltip-related bugs that were occurring when viewing items with 2 or more sockets in the auction house and profile pages
